BACKGROUND: Drug-related problems (DRPs) are prevalent among chronic kidney disease (CKD) patients. However, little is known about their severity and management by community pharmacists. OBJECTIVES: To (a) describe the prevalence of DRPs by severity level in CKD patients and (b) assess the effect of a training-and-communication network program in nephrology (ProFiL) on these DRPs. METHODS: This is a secondary analysis of a cluster randomized controlled trial evaluating the effect of the ProFiL-program. In 6 CKD clinics, patients at CKD stage 3 or 4 and their community pharmacists were recruited and assigned to the ProFiL group or a usual care (UC) group. Using validated criteria, 2 pharmacists identified DRPs and assessed their severity at baseline and after 12 months. The mean annual change in the number of DRPs per patient by severity level was assessed using a 2-level multivariable linear mixed-effects model. RESULTS: A total of 494 pharmacists and 442 patients participated. At baseline, the prevalence (mean number of DRPs per patient [SD]) of mild DRPs (e.g., requiring dosage adjustment) and moderate DRPs (e.g., drug adherence requiring a monitoring plan) were 0.55 (0.98) and 1.04 (1.51), respectively. After 12 months, an unadjusted incremental annual reduction of 0.34 moderate DRPs (95% CI = -0.66 to -0.01) was observed in the ProFiL group compared with the UC group. After adjustment, no between-group differences were observed. CONCLUSIONS: Among patients followed in CKD clinics, most DRPs have a moderate severity requiring specific monitoring by pharmacists. The benefit of continuing education programs, such as ProFiL, to reduce moderate DRPs remains to be determined.

Documentation of pharmacists' activities, such as drug related problems (DRPs) management, is necessary to estimate fair remuneration but is rarely done in community pharmacies. To document and evaluate the evolution of DRPs prevalence and management over six years. Observational study carried out since 2016 in a community pharmacy. Documentation was made yearly for 21 days (depending on seasons, holidays and medical internship rotations) using the ClinPhADoc tool. Pharmacists documented: medication, DRP type, intervention, implied partner and time for DRP management. A subanalysis was made depending on the medical rotation. A total of 171 437 prescriptions were received and 6 844 (4.0%) documented with 1 550 DRPs. Most frequent DRPs were procedural (n = 506, 32.6%), dosage/posology (n = 263, 17.0%) and drug-drug interaction (n = 153, 9.9%). Mean time dedicated to DRP management was 6.9 min, the longest time was for clinical DRPs (11.0 min, SD = 6.6). Most DRPs (n = 726, 44.6%) were managed by the pharmacist alone taking less working time than when involving other stakeholders (p < 0.01). Statistically significant differences were found in DRPs between the beginning and end of medical rotation (p < 0.05). Documentation of DRP management allowed consistent results over the years. Patterns of DRPs can be used to develop inter-professional interventions to prevent DRPs.
